The problem of early detection of sub surface lap joint corrosion in the fuselage section of aircraft is critical to the continued air worthiness of aging aircraft. The large area of lap joint to be inspected requires a high speed system of measurement. D SIGHT is an enhanced visual technique that allows rapid inspection and early detection of lap joint corrosion. Previously stored D SIGHT images, compared with current images can readily determine a change in a specific area of an aircraft, while constantly updating maintenance records. Nondestructive inspection of aircraft and other large complex structures using modern inspection devices leads to the generation of vast quantities of data, generally in an 'image' format. The types of inspection devices used in nondestructive inspection activities include but are by no means limited to ultrasound, eddy current, holography, D SIGHT and MOI. This paper describes a graphical user interface that has been implemented for data acquisition, storage, and retrieval of corrosion D SIGHT image data from aircraft lap splices. Features of this interface are described, as well as the benefits that can be realized from good data organization, presentation, and storage for monitoring and maintaining valuable capital assets.
